As a thought experiment, what would the reaction be if you handed the screener a piece of paper containing a form asking for their name, badge number or employee id, over a statement stating they were taking responsibility for your wallet and all contents, with a place for their signature. After which you trade the paper for your wallet, then vice versa at the other end, once you do an inventory.
